This leaks memory, if credW fails to allocate.
Something like this would work:

  +    WCHAR *dnW = NULL, *credW = NULL;
  +    int ret = LDAP_NO_MEMORY;
  +
  +    if (dn) {
  +        dnW = strAtoW( dn );
  +        if (!dnW) goto exit;
  +    }
  +    if (cred) {
  +        credW = strAtoW( cred );
  +        if (!credW) goto exit;
  +    }
  + ret = ldap_bindW( ld, dnW, credW, method );
  + exit:
  +    free dnW, credW
  +    return ret;
